MACHINE FOR MANUFACTURING METALLIC PACKING Filed Jan. 14, 1927lNlE/Y'IIOR 160/7 /Z 50/61" Patented Mar. 25, 1930 J UNITED STATESPATENT OFFICE i LEON. BLITEB, OI KALAMAZOO, MICHIGAN, ASSIGNOR TODURAMETALLIC CORPO- BATION, F KALAMAZOO, MICHIGAN MACHINE FORMANUFACTURING METALLIC PACKING Application an January 14, 1927. SerialNo. 161,102.

My improved machine is especially designed for the making of packings ofthe type shown in my application for Letters Patent filed concurrentlyherewith, Serial No. 161,101.

The main object of this invention is to provide a machineof the classdescribed by means of which packings may be rapidly formed from thinsheet metal or metal foil? in the form of strands with reinforcingspools 9 adapted to receive strips of metal foil or thin sheet metal 10,and a pluralit of spools 11 adapted to receive strands 12 0 reinforcingmaterial or the like.

This turret rotates within a housing 13 and is provided with steppedpulle s 14 adapted to e connected to the pulleys l by means of a beltnot illustrated. At the rear of this turret is a rotary former 15 havinga forwardly flaring guide 16, this former being rostrands incorporatedand interspersed there tatably mounted and provided with pulleys in thewhole aving a coverin of metal foil.

' A further object is to provi e an improved machine of the classdescribed by means. of which ackings of this type may be produced whichave very substantial tensile strength and enables the incorporation ofvarious materials with considerable uniformity.

Objects pertaining to details and economies of my impoved machine willdefinitely appear from the detailed description to follow. The inventionis clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearlyillustrated in the accompanying drawing forming a part of thisapplication, in which:

- Fig. 1 is a fragmentary perspective view of a machine embodyin thefeatures of my invention, the compacting formers and the reel beingomitted.

Fig. 2 is a side elevation, various parts being shown conventionally.

Fig. 3 is a side view of a'fragment or section of packing formed by myimproved machine.

Fig. 4 is a cross section on line H of Fig. 3.

Referring to the drawing, the main supporting frame 1 is provided with aplurality of pedestals 2 in proper spaced relation to support the parts.I have only shown such partsas are deemed necessary to illustrate myimprovements and certain of these parts are shown conventionally.

The driving shaft 3'is arranged longitudinally of the machine and isrovided with pulleys, 4, 5, 6 and 7, referab y stepped pulleys asillustrated. t the front end of the machine is a turret 8 carrying aplurality of 17 which are connected to the pulleys 6 by a suitable beltnot illustrated. The turret and former are mounted for independentrotation and adapted to be driven at different speeds.

The strips of metal 10 and the strands 12 are twisted together into astrand which is delivered axially through a second turret 18, thissecond turret being provided with a plurality of spools 19 adapted toreceive strips of thin sheet metal or metal foil 20, the strand 21formed by the'first turret and former being delivered to a second former22 so that the strips 20 are spirally twisted around the strand 20, thusproviding an outer twisted covering for this strand 21.

The turret 18 is provided with pulleys 23 which are driven b the pulleby means of the belt 26 while t e second ormer is rovided with pulleys24 which are driven rom the pulley 4 by means of the belt 25.

At the rear of the former 22 are reducing members 27 and 28, thesereducing members being of different diameters decreasing-toward the rearso that the twisted strand is compacted into the strand 29 which iswound upon a reel 30 shown conventionally. in Fig. 2. The material isdrawn throughthe machine by the pull of this reel.

The second twister 22 is also provided with a forwardly flaring guide 16which guides the strips into the twister gradually crumling andcompacting the metal as it is drawn into the twister.

My improved machine enables the making Y the same are bound togetheruniformly throughout.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1. In a machine of the class described, the combination of a rotatablymounted spool turret provided with a plurality of spools adapted toreceive strips of relatively thin metal mounted thereon and other spoolsadapted to receive reinforcing strands, a tubular rotatably mountedformer disposed at the rear of and in axial alinement with said spoolturret, a second rotatably mounted turret disposed at the rear of saidformer and provided with a plurality of spools adapted to receive stripsof relatively thin metal, a second rotatably mounted former disposed atthe rear of said second turret, and means for driving said formers andturrets at varying speeds.

2. In a machine of the class described, the combination of a pluralityof spool turrets disposed in spaced relation, each turret having spoolsadapted to receive strips of rela tively thin sheet metal, the firstturret being also rovided with spools adapted to receive rein orcingstrands, a rotating former disposed after each turret, each former beingprovided with a flaring guide projecting forwardly therefrom androtating therewith, and a plurality of forming members of varyingdiameters decreasing toward the rear arranged at the rear of therearmost former.

3. In a machine of the class described, the combination of a pluralityof spool turrets disposed in spaced relation, each turret having spoolsadapted to receive strips of relatively thin sheet metal, the firstturret being also rovided with spools adapted to receive rein orcingstrands, and a rotating former adapted to receive strips of relativelythin metal and other spools adapted to receive reinforcing strands, theseveral spools being arranged in a circle, a tubular rotatably mountedformer disposed at the rear'of and disposed after each turret, eachformer being provided with a flaring guide projecting forwardlytherefrom and rotating therewith.

4. In a machine of the class described, the

combination of a plurality of spool turrets disposed one at the rear ofthe other and each having a plurality of spools, a former dis posed atthe rear of each turret and rotatable independently thereof, means forrotating said turrets and formers at difierent speeds,

and a plurality of forming members of varying dimensions decreasingtoward the rear arranged at the rear of the rearmost former.

5. In a machine of the class described, the combination of a pluralityof spool turrets disposed one at the rear of the. other and each havinga plurality of spools, a former disposed at the rear of each turret androtatable independently thereof, and means for rotating said turrets andformers at different speeds.

6. In a machine of the class described, the combination of a rotatablymounted spool turret provided with a plurality of spools
